Updated Changes file to be conformant with CPAN::Changes::Spec

Hi,

I added the date for the 0.012 release -- not having the date was causing it to fail against testing for CPAN::Changes::Spec. I got the date from backpan.

Following this format means that various tools can more easily process your distribution automatically.

You can find out more about this at Brian Cassidy's CPAN::Changes Kwalitee Service (http://changes.cpanhq.org), which is where I saw your module listed :-)

Cheers,
Neil
